The overcurrent release is an ETU320 electronic trip unit, which gives adjustable pickup and time-delay settings for coordination. That is useful for emergency-stop circuits or undervoltage protection on motor feeders. This MCCB's interrupting rating depends on the system voltage you feed it. At 240 V it can clear 187 kA; at 415 V or 440 V it handles 121 kA; at 500 V it drops to 75.6 kA; at 690 V it still holds 17 kA. The 17 kA at 690 V covers most 690 V motor-control applications. ## Thermal derating — how hot can your panel get? At 55 °C it derates to 384 A, at 60 °C to 376 A, at 65 °C to 368 A, and at 70 °C to 360 A. Factor it into your thermal calculation when grouping multiple breakers. Depth of 110 mm means it clears typical enclosure back-panel clearance.","metaTitle":"Siemens 3VA2440-5HL32-0CA0 SENTRON MCCB, 400 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0CA0 molded case circuit breaker, 400 A rated continuous current, 3-pole, line protection, ETU320 release, 187 kA at 240 V.
